Hi, I have read about the lenses, was just looking around. In my country someone has a T* black lens 80mm with red numbers on the barrel. Is that different to a CT*? The picture looks different to Keh's at least.
To my knowledge: The Black "C" lenses were all T* lenses, while some of the earlier Silver ones were not. Optically I understand these to be the same as the later CF lenses but with a different shutter.
